Help

Madalas nyo rin po ba naranasan o nararanasan ang nausea, mild headache minsan/ pagkahilo, laging inaantok/tulog. And yung urge na parang masusuka ka nalang pag nakaka kita ng ibang pagkain, loss of appetite din. Please tell me how to cope with these symptoms. I am currently 4 weeks pregnant and a 20yrsold woman
